Copper-clad steel wire and strand combines copper's electrical characteristics with steel's mechanical properties. Often used for buried ground grid systems, overhead ground wire, and messenger wire, it can resist mechanical damage during installation and electrical damage during a fault condition. Copper Clad steel has virtually no scrap value, and is extremely difficult to cut with traditional wire and cable-cutting tools, greatly reducing the potential of theft.
